The corpse which you see here is that of M. Bayard, inventor of the process that has just been shown to you. As far as I know this indefatigable experimenter has been occupied for about three years with his discovery. The Government, which has been only too generous to Monsieur Daguerre, has said it can do nothing for Monsieur Bayard, and the poor wretch has drowned himself. Oh the vagaries of human life...!
(1840, written on his self-portrait as a drowned man made after he was beaten to the announcement of the discovery of photography by Louis-Jacques Mandé Daguerre.)
